BACKGROUND Although the benefits of exercise for kidney transplant recipients(KTRs)have been widely demonstrated,these patients experience several barriers in undertaking a structured exercise program in hospital and non-hospital *** To compare the effects of a supervised moderate-intensity gym-based intervention with a home-based low-intensity walking program on exercise capacity in *** KTRs were asked to choose between two six-month *** first group performed a low-intensity interval walking intervention at home-based exercise intervention (HBex). The second group performed a supervised training program at an adapted physical activitygym (Sgym), including aerobic and resistance training. The outcomes, collected at baseline and at the end of theprograms, included the 6-minute walking test, the peak oxygen consumption (VO_(2)peak) during a treadmill test,the 5-time sit-to-stand test, and blood *** patients agreed to participate and self-selected into the HBex (n = 9) and Sgym (n = 8) groups. Twopatients in the Sgym group dropped out because of familial problems. At baseline, patients in the HBex group weresignificantly older and had lower walking distance, VO_(2)peak, and lower limb strength. Primary outcome changeswere significantly greater in the HBex group than in the Sgym group (52 ± 23 m vs 8 ± 34;P = 0.005). No othersignificant differences between groups were observed. Both groups improved most of the outcomes in the withingroupcomparisons, with significant variations in VO_(2) ***-month moderate-intensity supervised or low-intensity home-based training programs effectively improvedexercise capacity in KTRs. Gym-based programs combine aerobic and resistance training;however, in-homewalking may be proposed for frail KTRs.

Dear Editor,The problem of age estimation in amphibians and reptiles with annual fluctuations of growth pattern has been considered to be mostly solved since the skeletochronological method was introduced(Kleinenberg and Smirina,1969).This method is based on counting the number of lines of arrested growth(LAGs)—cyclical growth marks that are usually formed annually and characterized by different optical aspects within the tubular bones.
